There are 3 distinct ratings to familiarize yourself with: dry, damp, and wet. Dry locations: an area where some dampness could occur but because of ventilation, helps reduce moisture, such as kitchens, living rooms, and dining rooms. Damp locations: an area where some moisture and condensation can build up, normally bathrooms. Wet locations: an area where water or liquids may drip more often, such as open decks, stairwells, and patios.
